I figur l illustreras en byggnad l, exempelvis en skol- byggnad med lokaler 2 och 3, exempelvis skollokaler.Figure 1 illustrates a building 1, for example a school building with premises 2 and 3, for example school premises.
Byggnaden l uppvisar ett bottenbjälklag 5 som är anord- nat pà en bädd Sa placerad pà marken 4 under byggnaden 1. Bädden Sa bestàr av ett övre skikt Sb av stenmate- rial, t.ex. makadam, och ett nedre skikt Sc av annat sten- och/eller grusmaterial. Bädden Sa uppvisar före- trädesvis ett djup pà ca. 30 cm, varvid det övre skik- tet Sb är ca. 20 cm och det nedre skiktet Sc ca. 10 cm.The building 1 has a bottom floor layer 5 which is arranged on a bed Sa located on the ground 4 below the building 1. The bed Sa consists of an upper layer Sb of stone material, e.g. macadam, and a lower layer Sc of other stone and / or gravel material. The bed Sa preferably has a depth of approx. 30 cm, the upper layer Sb being approx. 20 cm and the lower layer Sc approx. 10 cm.
Mellan lokalerna 2 och 3 är anordnat ett mellanbjälk- lag 6. 510 842 För att sommartid kyla bottenbjälklaget 5 och mellanbjälk- laget 6 finns en kylanordning 7 innefattande ett utom- hus placerat kylaggregat 8. Detta uppvisar en fläktanord- ning 9 och ett kylvätskesystem 10 med en kylvätska som företrädesvis innehåller ett antifrysmedel, t.ex. glykol, för att skydda kylvätskesystemet 10 frän att frysa sön- der pà vintern. Kylvätskesystemet 10 samverkar med en första värmeväxlare 11 och med denna samverkar ocksa ett rörsystem 12, vilket är kommunicerande förbundet med ett ledningssystem 13, som är förlagt i bottenbjälklaget 5 och/eller i bädden 5a samt i mellanbjälklaget 6. Led- ningssystemet är freon- och kompressorfritt.Between the rooms 2 and 3 an intermediate floor layer 6 is arranged. 510 842 In order to cool the bottom floor layer 5 and the intermediate floor layer 6 in summer, there is a cooling device 7 comprising an outdoor cooling unit 8. This has a fan device 9 and a cooling liquid system 10. with a coolant which preferably contains an antifreeze, e.g. glycol, to protect the coolant system 10 from freezing in winter. The coolant system 10 cooperates with a first heat exchanger 11 and with this also cooperates a pipe system 12, which is communicatively connected to a pipe system 13, which is located in the bottom floor layer 5 and / or in the bed 5a and in the intermediate floor layer 6. The pipe system is freon- and compressor free.
Syftet med nämnda kylanordning 7 är att sommartid under natten med hjälp av fläktanordningen 9 transportera kylig nattluft genom kylaggregatet 8 för att kyla kylvätskan i kylvätskesystemet 10. Den kylda kylvätskan ledes via kylvätskesystemet 10 till den första värmeväxlaren 11 och kyler däri den i rörsystemet 12 och ledningssystemet 13 befintliga vätska 14, som företrädesvis utgöres av vatten eller en blandning bestående av i huvudsak vatten.The purpose of said cooling device 7 is to transport cool night air through the cooling unit 8 during the summer by means of the fan device 9 to cool the coolant in the coolant system 10. The cooled coolant is led via the coolant system 10 to the first heat exchanger 11 and cools it in the pipe system 12 and conduit 13 existing liquid 14, which is preferably constituted by water or a mixture consisting essentially of water.
För att kunna kyla lokalen sommartid under en hel arbets- dag, d.v.s. upp till ca. 8 timar, med full eftersträvad kapacitet, bringas den kylda vätskan 14 att under natten förutom att kyla bottenbjälklaget 5 ocksa kyla bädden 5a tills sàväl bottenbjälklaget 5 som bädden 5a kylts ned tillräckligt. Den av sàväl bottenbjälklaget 5 som bäd- den 5a bestående ackumulatorn är tillräckligt stor för att kyla lokalen 2 pà nämnt sätt, d.v.s. upp till ca. 8 timmar. vätskan 14 bringas kyla bädden 5a till ett djup pà àtmins- tone ca. 20 cm., företrädesvis ca. 30 cm, varigenom det övre skiktet 5b kylts ned i hela dess djup och det nedre skiktet 5c i àtminstone större delen av dess djup. 510 842 Vidare kyles såväl bottenbjälklaget 5 som bädden 5a i hela eller i huvudsak hela dess längder och bredder.To be able to cool the room in summer during an entire working day, i.e. up to approx. 8 hours, with full desired capacity, the cooled liquid 14 is caused to cool the bed 5a during the night in addition to cooling the bottom floor 5 until both the bottom floor layer 5 and the bed 5a have cooled down sufficiently. The accumulator consisting of both the bottom floor 5 and the bed 5a is large enough to cool the room 2 in the manner mentioned, i.e. up to approx. 8 hours. the liquid 14 is brought to cool the bed 5a to a depth of at least approx. 20 cm., Preferably approx. 30 cm, whereby the upper layer 5b is cooled down in its entire depth and the lower layer 5c in at least most of its depth. Furthermore, both the bottom floor 5 and the bed 5a are cooled in all or substantially all of its lengths and widths.
Vätskan 14 kan bringas kyla bottenbjälklaget 5 i riktning nedifrån och upp och samtidigt bädden 5a i riktning uppi- från och ned. Lämpligen kan vätskan 14 ledas genom sådana nedre delar av bottenbjälklaget 5 som befinner sig in- till den underliggande bädden 5a. Även mellanbjälklaget 6 och därmed lokalen 3 kyles under natten.The liquid 14 can be brought to cool the bottom floor 5 in the direction from below and up and at the same time the bed 5a in the direction from the top down. Conveniently, the liquid 14 can be passed through such lower parts of the bottom floor 5 which are located inside the underlying bed 5a. The intermediate floor 6 and thus the room 3 are also cooled during the night.
För att vintertid värma upp bottenbjälklaget 5 och even- tuellt bädden Sa samt mellanbjälklaget 6 finns en upp- värmningsanordning 15 innefattande ett värmesystem 16, t.ex. ett fjärrvärmesystem eller eventuellt en värmepanna, vilket samverkar med en andra värmeväxlare 17. Med denna samverkar också ett rörsystem 18, vilket också är kommu- nicerande förbundet med ledningssystemet 13.In order to heat the bottom floor layer 5 and possibly the bed Sa and the intermediate floor layer 6 in winter, there is a heating device 15 comprising a heating system 16, e.g. a district heating system or possibly a boiler, which cooperates with a second heat exchanger 17. A pipe system 18 also cooperates with this, which is also communicatively connected to the line system 13.
Syftet med nämnda uppvärmningsanordning 15 är att vinter- tid i den andra värmeväxlaren 17 överföra värme från värmesystemet 16 till vätskan 14 i ledningssystemet 13 för att värma upp bottenbjälklaget 5 och mellanbjälk- laget 6 och därmed luften i lokalerna 2 och 3.The purpose of said heating device 15 is to transfer heat from the heating system 16 to the liquid 14 in the pipe system 13 in the second heat exchanger 17 to heat the bottom floor layer 5 and the intermediate floor layer 6 and thus the air in the rooms 2 and 3.
För att effektivt säkerställa att ingen fuktvandring sker från marken 4 upp genom bottenbjälklaget 5 kyles detta och bädden Sa så att åtminstone övre delar av bottenbjälk- laget 5 erhåller en sådan lägsta temperatur som väsentligt överstiger i marken 4 rådande marktemperatur. Detta kan utföras på olika sätt, t.ex. genom att ifrågavarande delar dimensioneras eller utformas härför eller genom att an- passa ifrågavarande vätskeflöde härför och/eller genom att det finns en regleranordning 19a härför i kylanord- ningen 7 eller på annat lämpligt ställe.In order to effectively ensure that no moisture migration takes place from the ground 4 up through the bottom floor layer 5, this is cooled and the bed Sa so that at least upper parts of the bottom floor layer 5 obtain such a minimum temperature which substantially exceeds the ground temperature prevailing in the ground 4. This can be done in different ways, e.g. by dimensioning or designing the parts in question for this or by adapting the liquid flow in question for this and / or by having a control device 19a for this in the cooling device 7 or in another suitable place.
Eftersom årsmedeltemperaturen i mark 4 är ca. 8°C är mark- temperaturen något lägre på vintern och något högre på 510 842 sommaren. För att hindra nämnda fuktvandring pá somaren kyles bottenbjälklaget 5 och bädden Sa lämpligen till en lägsta temperatur ej understigande ca. l6°C och pà vintern värmes bottenbjälklaget 5 till en temperatur som ligger väsentligt högre, lämpligen ca. 25-26°C. Fastställande av den lägsta temperaturen i bottenbjälklaget 5 vintertid kan också ske pà olika sätt, t.ex. med hjälp av en regler- anordning l9b.Since the annual average temperature in soil 4 is approx. At 8 ° C, the ground temperature is slightly lower in winter and slightly higher in 510,842 in summer. In order to prevent said moisture migration in the summer, the bottom floor 5 and the bed Sa are suitably cooled to a minimum temperature not less than approx. 16 ° C and in winter the bottom floor 5 is heated to a temperature that is significantly higher, preferably approx. 25-26 ° C. Determination of the lowest temperature in the bottom floor 5 in winter can also take place in different ways, e.g. by means of a control device l9b.
Ledningssystemet 13 är lämpligen placerat ovanpà bädden 5a, t.ex. pà det övre skiktet 5b eller företrädesvis pà ett isärhàllningsskikt 21, t.ex. en fiberduk, som är pla- cerat pà det övre skiktet 5b. När ledningssystemet 13 är placerat pà detta sätt gjutes ett gjutskikt 22, t.ex. av betongmaterial, ovanpà bädden 5a eller företrädesvis ovanpå isärhàllningsskiktet 21 och ledningssystemet 13 sá att kylning sker i riktning uppåt genom bottenbjälk- laget 5 och samtidigt i riktning nedát genom bädden 5a.The conduit system 13 is suitably located on top of the bed 5a, e.g. on the upper layer 5b or preferably on a separating layer 21, e.g. a nonwoven fabric, which is placed on the upper layer 5b. When the conduit system 13 is placed in this way, a casting layer 22 is cast, e.g. of concrete material, on top of the bed 5a or preferably on top of the separation layer 21 and the pipe system 13 so that cooling takes place in the upward direction through the bottom floor layer 5 and at the same time in the downward direction through the bed 5a.
I mellanbjälklaget 6 är ledningssystemet 13 lämpligen placerat pá en armeringsanordning 23, t.ex. ett armerings- nät, som är anordnad i den övre delen av mellanbjälklaget 6 eller i huvudsak i denna. Härigenom kommer lednings- systemet 13 också att befinna sig i exempelvis en övre tredjedel av mellanbjälklaget 6. Lämpligen placeras led- ningssystemet 13 pà armeringsanordningen 23 innan gjut- ning av mellanbjälklaget 6 och därefter fylls betongmate- rial i formen för att färdigställa detta.In the intermediate floor 6, the conduit system 13 is suitably placed on a reinforcing device 23, e.g. a reinforcing mesh, which is arranged in the upper part of the intermediate floor 6 or substantially in it. As a result, the pipe system 13 will also be located in, for example, an upper third of the intermediate floor 6. Preferably, the pipe system 13 is placed on the reinforcement device 23 before casting of the intermediate floor 6 and then concrete material is filled in the mold to complete this.
Ledningssystemet 13 uppvisar företrädesvis átminstone en böjlig slang 24 av sádant gummimaterial eller sàdant mot- svarande material att vätskan 14 inte kan komma i kontakt med omgivande material i bottenbjälklaget 5 och bädden 5a eller i mellanbjälklaget 6. Slangen 24 kan böjas manuellt till lämplig form sa att den löper i bottenbjälklaget 5 och mellanbjälklaget 6 som slingor i en ledning som sak- 510 842 nar skarvställen. I det visade utförandet uppvisar led- ningssystemet 13 làngsträckta dubbelslangenheter 25, som är manuellt böjbara och som uppvisar tvà parallellt med .varandra förlöpande slangar 24, vilka är förbundna med var- andra via manuellt böjliga förbindelsedelar 26 av samma material som slangarna 24.The pipe system 13 preferably has at least one flexible hose 24 of such rubber material or such corresponding material that the liquid 14 can not come into contact with surrounding material in the bottom floor layer 5 and the bed 5a or in the intermediate floor layer 6. The hose 24 can be bent manually to a suitable shape so that it runs in the bottom floor layer 5 and the intermediate floor layer 6 as loops in a line that lacks 510 842 splicing points. In the embodiment shown, the conduit system 13 has elongate double hose units 25, which are manually bendable and which have two parallel hoses 24, which are connected to each other via manually flexible connecting parts 26 of the same material as the hoses 24.
Eventuell överskottsvärme som erhålles vid nämnda förfa- rande kan användas för att värma upp luft som bláses in i lokalen eller lokalerna med hjälp av en fläktanordning (ej visad).Any excess heat obtained in said process can be used to heat air which is blown into the room or rooms by means of a fan device (not shown).
Det ovan beskrivna förfarandet och den ovan beskrivna anordningen kan variera inom ramen för efterföljande patentkrav. Sàlunda kan bädden 5a besta av annat mate- rial än ett eller flera skikt placerade pà marken. Som exempel pà en alternativ bädd kan nämnas en naturlig berggrund eller liknande. Det är ocksà möjligt att i vissa fall använda annat medium 14 än vätska för kylning/ /uppvärmning av bottenbjälklaget 5 och bädden Sa samt eventuellt mellanbjälklaget 6, det kan finnas mer än ett mellanbjälklag 6 som kyls/värms om byggnaden har fler vaningar och ledningsystemet 13 kan vara av annan typ av ledningssystem än en böjlig slang eller flera sàdana.The method described above and the device described above may vary within the scope of the appended claims. Thus, the bed 5a may consist of material other than one or more layers placed on the ground. An example of an alternative bed is a natural bedrock or similar. It is also possible in some cases to use another medium 14 than liquid for cooling / / heating the bottom floor 5 and the bed Sa and possibly the intermediate floor 6, there may be more than one intermediate floor 6 which is cooled / heated if the building has more vans and the pipe system 13 may be of a different type of conduit system than a flexible hose or several such.
Vidare är det ocksa möjligt att leda nämnda medium 14 genom sàväl bottenbjälklaget 5 som bädden Sa eller even- tuellt endast genom bädden Sa. Det är ocksa möjligt att i vissa fall förutom bottenbjälklaget 5 och bädden 5a kyla underliggande mark 4.Furthermore, it is also possible to guide said medium 14 through both the bottom floor layer 5 and the bed Sa or possibly only through the bed Sa. It is also possible in some cases, in addition to the bottom floor 5 and the bed 5a, to cool the underlying soil 4.
